HYDRAULIC RAIL-BONDING TOOL.

PECIFICATION forming part Of Lette s P81761113 763,531, dated June 28, 1904.

Application filed December 20, 1899. Serial No. 740,973. (No model.)

To all whom it may concern.-

Be it known that I, CARL WIGTEL, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented a certain new and useful Improvement in Hydraulic Rail -Bonding Tools, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, forming par-t of this specification.

This invention relates to improvements in hydraulic tools which comprise a ram in the lower part of the body, the face of the ram being upward and a jaw projecting over the ram;rand the invention consists of a hydraulic tool and mechanism appertaining thereto constructed or constructed and combined as herein described and claimed.

On the accompanying sheets of drawings, Figure 1 is side elevation of a riveting-tool and supplemental mechanism, a vertical section of a support on which they are mounted, and a fragment of a cross-section of an electric railway, the tool being shown hung in a manhole of the railway readyto act on a bondrivet in one of the conductor-rails; Fig. 2, a front elevation of the tool and supplemental mechanism and parts of the support and fragments of a longitudinal section of the railway crossing the manhole; Fig. 3, a sectional detail of certain devices attached to the top of the head of the tool, and Fig. 4 a side elevation ofthe-head and body of the tool and a vertical section of a tool-base and 'railsup port.

-Similar reference-numerals designate like parts in different views.

The main object of this invention is toproduce a hydraulic tool so constructed and combined with supplemental mechanism as to render it fit for use in manholes of an electric railway in installing rail-bonds in conductorrails fixed in a conduit below the level of the track. The interior of a manhole being small and the yokes, slot-rails, insulators, supporting-brackets of the conductor-rails, and other parts of the underground structure obstructing access to the conductor rails except through small spaces, a tool to be fit for the use contemplated must have various peculiarities in form and arrangement of parts and should be capable of being operated from above the track, Where there is plenty of room.

Although the particular tool shown is a bond-riveting tool, yet the main features of the invention might be embodied in a press comprising instead of a rivet-set a device of another form or in a punching-tool, a punch being substituted for the rivet-set and a die being fixed in a hole in the jaw overhanging the ram, as appears by an application for a patent for a hydraulic punch filed May 19, 1899, and bearing the serial number 717A52, and the invention is accordingly claimed with the intention of securing it not only in the precise form shown, but in all mere modifications thereof.

The body of the tool is a steel casting composed of the trunk 1, the ram-cylinder 10, formed on and in front of thelower part of the trunk, the jaw 11, projecting over the ramcylinder, and the stock 12, formed on the rear part of the top of the trunk, the stock 12 and end of the hole 13 is closed by a screw-plug.

The rivet-set l4, fixed on the ram, projects far enough from the ram to insure its proper action on the bond-rivet, although the face of the ram is not raised quite to the rail. A handle 15 is attached to the back of the tool.

Onthe body is a head 2, which is screwed intothe stock- 12 and which contains a pump that is actuated by a handle-bar inserted in the socket 2. The axis of the head coincides with the prolonged axis of the stock, and the interior of the head communicates with the passage 13 13. The top of the head is a screw-plug 20, having the form shown in Fig.

3, its stem being composed of the plain cylindrical section 21, the smaller threaded section 22, and the still smaller plain section 23. On the section 21 of the stem is aloose collar 25, on which is a slotted projection 25, containing a hole in which fits a pin 26. This collar is confined on the stem of the plug by means of a washer 21 and a nut 22. The weights of the several parts of the tool are so proportioned that the center of gravity of the tool, which is below the collar 25, lies in the median plane of the tool or the plane containing the axes of the head and ram and between those axes, its distance in front of the axis of the head being equal to that of the axis of the pin 26 from the axis of the head. A hook 27 is pivoted on the pin 26 in the slot in the.

projection 25, the hook being properly formed and being at a proper distance above the jaw 11 to engage a slot-rail when the tool is in a proper position to act on a conductorrail in the conduit, as appears by Fig. 1.

The support from which the tool hangs consists of two bars 3 of wrought iron or steel, bent as shown by Figs. 1' and 2 and secured together by pins 30, on which are separators like the sleeve 31, (shown in Fig. 1,) the bars being held by the pins in contact with the ends of the separators. The support is longer than the distance across a manhole and stands with two of its feet 3' on one side and its other two feet on the opposite side of the manhole, in which the tool hangs. Blocks 32 are fastened between the bars3 by pins 32, and to these blocks handles 33 are pivoted.

A truck composed of a block 4, on which are axles 1, and of grooved wheels 40 on the axles, is mounted on the support, which provides a track along which the truck may be easily moved. Through an unthreaded hole in the block at and between the bars 3 of the support passes a screw 5, to which is attached a crank 50, the screw being loose in the block and having a head or fixed collar 5, which rests on the top of the block and by which the screw hangs. On the lower part of the screw is a yoke 51, with which the screw engages in a screw-threaded hole extending through the top of the yoke. This yoke is pivoted to the projection 25 on the head of the tool by the pin 26 passing through the sides 51 of the yoke, the projection and rear end of the hook 27 being within the yoke. V

The tool naturally assumes an upright position under the action of its center of gravity, with the axes of the head and ram vertical when it hangs from the support with its median plane at right angles to the axis of the pin 26, since it swings freely on the axes of the pin 26 and the axles 4:, which axes are above the center of gravity and intersect a straight line drawn through it parallel to the axes of the head and ram, and the tool may be turned on the axis of the head, the stem of the plug 20 turning in the collar 25, and may be raised and lowered on the screw. The tool is lowered into the manhole by the handles 33 of the support, and then the hook 27 is engaged with the slot-rail 6, and the tool is further adjusted, if necessary, by moving the truck and turning the tool on the axis of the head by the handle 15, the screw being so adjusted that the ram and jaw 11 pass under the base of the slot-rail and the jaw passes over and the rivet-set under the bond-rivet in the conductor-rail 7. The adjustment of the tool is completed by turning the screw and lower ing the tool until the jaw is in firm contact with the head of the bond-rivet. The tool is lowered into and adjusted in the manhole from above the manhole. It is also operated from above the manhole.

The bond-rivet is upset by the action of the ram and rivet-set thereon, the ram being forced upward by pumping fluid from the head into the ram-cylinder through the passage 13 13. The ram is then depressed by drawing the head and body of the tool upward by means of the screw 5, the ram-cylin der being thus raised on the ram, and afterward lowering the tool.

The hook 27 not only serves as a gage to facilitate the adjustment of the tool as described, but constitutes also a tie that prevents the top of the tool from being pulled backward in the operation of the tool by the force exerted on the handle-bar which actuates the pump and which extends upward and backward over the manhole.

The tool-base and rail-support shown in Fig. 4 is used with the tool when rail-bonds are installed or partly-installed in the conductorrails before these rails are put into the conduit. This device is composed of a flat block 8, of wood or metal, on which are a collar 80, a post 81, and rail-rests on opposite sides of the collar, each consisting of a bent piece of iron 82, fastened at its ends to the block. The collar fits around the bottom of the ram-cylinder, and the post helps to support the tool, as shown, there being in the collar a set-screw 80 and in the post a pin 81, that'enters a hole in the body of the tool. The rail is supported by the rail-rests, as appears by the drawings, during the operation of the tool on the railbond.
